* Use product icons instead of 'hardcoded' icons

- Add a product icon font instead of icons that are unchangable by product icon themes
- Add a script using FontForge scripting API for generating product icon font for future use
- Remove redundant icons that are already part of codicons

* Revert accidental addition of 'languages' contribution entry
